CHARLES H. GLOWER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO CRUSE- KEMIER COMPANY, OF AMBLER, PENNSYLVANIA, A CORPORATION OF PENN- SYLVANIA.

GAS-PURIFYING APPARATUS.

To all whom it may concern Be it known that 1, CHARLES H. CLoWER, a citizen of the United States, and a resident of the city of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Gas-Purifyin Apparatus, of which the following is a specification.

In gas or vapor purifying apparatus as heretofore constructed it has been a difficult and expensive matter to remove the iron oxid from its containers after the same has been used. The practice heretofore has been for a workman to enter a chamber with a pick or other implement and loosen up the more or less granular material and remove,

the same in small portions. 7 r

It is one of the objects of my invention to avoid this expensive operation by proand with a minimum amount of labor.

A further object of my invention is to provide an improved construction of container by the employment of vwhich the amount of iron oxid purifying material required is reduced and the purification of the gas or vapor passing through the materialtherein is facilitated.

A still further object of my invention is to provide an improved construction of container,one which may be readily collapsed purifying and thereby reduce to a'minimum the cost.

of discharging or removing the compactvand hard purifying material therefrom.

Other objects and advantages of my invention will be referred to and pointed out in the detailed description thereof which'follows or will be apparent from such description.-

In order that my invention may be more Figure 1 is aview partly in vertical sec- Serial No. 37,801.

tion and partly in side elevation of an apparatus embodying my invention; Fig. 2 is a view partly in vertical section and partly in elevation taken at right angles to the view shown in Fig. 1; and Fig. 3 is a section View taken on the line 33 of Fig. 1 showing a detail of construction.

Referring to the drawings, 1 designates a base or foundation of suitable construction on which the apparatus is supported and 2 designates an inclosure or casing withiir which the iron oXid container and other apparatus, to which reference will be hereinafter made, are situated. As is apparent from Fig. 2 of the drawings the casing or inclosure is divided into compartments separated by transversely extending platesfsuch as 3, and within each of these compartments the containers for holding purifying materialland'other apparatus are situated. The gas purifying material is held in containers which respectively comprise side frame structures which are adaptedto be. detachably secured together so that they may be readily separated to thereby facilitate the discharge and removal of the condensed and compacted purifying material, such as-iron oxid,therefrom.j v

The side frame structures of the containers will beconsidered and described in pairs.

First I shall describe thesidewall which is shown in elevation at the right hand side of Fig. 2 of the drawings, itjbeing understood that theopposing side wall isidentical in construction. Each of thesevside walls comprisesangle irons at at its opposite sides which are connected with each other by means of angle irons 5' and 6, the first being situated at the tops of the said angle irons 4: and the second a distance, as, shown, above the. lower ends of the said angle irons 4. In order to brace the connection between the said angle irons, have provided the two diagonal: strips 7 and 8 which extend between diagonal corners of the frame forming the side walls .of thefcontainer. The ends of said. strips 7 and 8 are connected with the ends of said angle irons by means of the connecting plates 9. The bottom angle irons 6 are connected together by means of the transversely extending angle irons 10. The connection between the angle irons Sand 10 is effected by means of the screw- 1 threaded bolts and nuts .10. By removing the latter the said angle irons are disconnected. In Fig. 1 is illustrated in side elevation one of the other two side walls each of whichcomprises the angle irons 11 which are connected at top and bottom by means of the cross angle irons 12 and 13. These angle irons 12 and 13 are secured at their opposite ends to the angle irons 11 by means of the connecting plates 14. 15 and 17 designate braces extending diagonally between the corners of the frame constituting the walls. The construction of these two last mentioned side walls is the same.

It will be observed that the angle irons 11 are situated within the angles of the angle irons a, the relative arrangement being clearly shown in Fig. 3 of the drawings. These side frame structures are secured or bound together by means ofrods 18 which pass through holes 18- in the outer edges of one of the flanges of each of the angle irons 4L. The flanges containing these holes or openings are relatively wide asis shown in Fig. 3 of the drawings. It is apparent that whenthese rods are in place and when the nuts 19 are screwed into position thereon the several side frames constituting the support ing side walls of the container are securely but detachably bound. together. Situated within these side frames is what may be termed a lining consisting ofgroups of slats secured together, one group constituting the bottom and-the other groups, four of them, constituting the lining for the foursides of the container. These slats are connected together by means of rods 20, the slats in each group being separated from each other by meansof separating sleevesor collars 21. It will be observed that the group of slats constituting the bottom of the container are first placed in position being supported on flanges 22 on the lower angle irons 6 and 13 and the crosswise angle irons 10 and that the lower ends of therespective groups of slats constituting the side portions of the container lining stand or restupon the bottom slats. These slats being separated from each other permit the free passage therethrough of the gas so that it may freely enter and percolate through the purifying material 23., such as iron oxid, contained therein. The slats while being separated so as to permit the free passage therethrough of the gas which is to be purified and cleansed are sufficiently close together to securely hold and retain the iron oxid therein.

In order that the containers either filled or unfilled with the iron oXid or other purifying agent may be placed'in position within the compartments of the inclosure or casing 2 each of the said compartments is provided with a door 25 hinged as at 26 to one edge of the top wall of such compartment. In Fig, 1 of the drawing the saiddoor 25 is shown in fulllines in open position and in dotted lines in closed position.

When in closed.

position it is adapted to be fastened around its edges by means of a toggle acting fastener 27 which is hinged at 28 to a bracket 29 depending from the sides of the casing.

It may be noted that the casingor inclosure 2 whenthe door 25 is closed is hermetically sealed by means of a gasket around theedges so that it is gas tight.

The means shown in the accompanying drawing for introducing the containers into and removing the same from acompartment consists of a truck 30 which is adapted to be moved into and out of the compartment upon tracks31. The truck 30 is provided with a platform 32 which is supported upon parallel links 33 which are pivotally con;

nected with the truck '30.

In the position occupied by the platform is illustrated in Fig. 1 of the drawing,

the container is supported by means of the lower ends of the angle irons 4t and 11 upon the bottom wall of the casing or inclosure2 and is not supportedby the said platform. hen it is desired, however, to lift the plat form and consequently lift the container so.

as to remove the lower ends of the said angle irons 4: and 11 from the bottom of the casing or inclosure 2 the said platform is moved toward the front of the truck, that is, toward the left, having reference to Fig. 1 of the drawing. Such movement is accompanied by a simultaneous, upward movement. Both of these movements are occasioned by means of a worm 35 having engagement with a worm gear 36 which in turnengages. a

gear upon a shaft 37 carrying a drum 38 upon which is wound a rope 4C0 having connection with the forward end of the platform 32. The worm 35 is rotated by means of a hand wheel #11. By. rotating the latter to wind the drum 38 toward the left it will be understood that the rope s'O is wound up on the said drum soas to draw the platform 32 forward and thereby cause a lifting-move ment of the container together with any purify-ing material contained therein.

The container with the iron oxid or other purifying material therein having. been liftedso as to raise the lower ends of the angleirons a and 11 from the bottom of the casing or inclosure the'truck may be pulled forward along the track 31 to transport the container and the purifying material therein to such point as may be desired. Other suitable means than that shown may be eniirons 6 and perm itting or causing the several sides of the container to fall outwardly away from the purifying material contained therein.

A container having therein a new charge of iron oxid or'other purifying material may be inserted into a compartment by means of the truck in an obvious manner.

It will be noted that the central portion of the rear of the truck as well as of the platform 32 is removed so that when the truck is moved into position underneath the container the opposite sides of the rear portions thereof pass upon opposite sides of the tubular outlet constituting a duct through which the gas passes from one compartment to another or from a compartment to a reservoir or tank.

The gas to be purified passes into a compartment through a gas inlet 16. Having reached the compartment it passes between the slats upon the sides and bottom of the container as well as from the top into the iron oxid or other purifying material pres ent in the container. It percolates through this material and enters the tubular outlet 45 through a head 47 having openings therein which is situated within and is surrounded by the said purifying material. In the construction shown the head consists of curved slats secured together and spaced from each other as shown. Preferably such head should be situated at a convenient distan'ce below the center of the container in order to secure the best results. \Vhen so situated substantially the same amount of gas enters the said head from all directions. If it were situated near the top of the iron oXid or other purifying material the tendencv of the gas would be to follow the line of least resistance and flow from the top downwardlv'through the upper portions of the purifying material into the said head with the result that a large proportion of the lower more solid and compacted por tions of said material would not be used to the extent necessary to secure available efiiciency.

It will be observed that the tubular outlet 45 is provided intermediate its ends with an'annular flange 50' which is secured by means of bolts to the adjacent flanges of two of the angle irons 10 which extend between the side angle irons 6. It will be understood that one of these tubular outlets is provided for each of the containers in each of the compartments of the casing or inclosure. The lower flanged end of each of these tubular outlets rests upon a 'compressible gasket 51 which is situated in an opening 52 formed in the bottom wall of a'compartment of the casing or inclosure and which is supported in a seat 53 which surrounds an opening 54 formed in an outlet member 55 secured upon the lower side of the casing or inclosure by means of rivets 56. The hole or opening 54 in the outlet member 55 is in alinement with the opening 52 and with the tubular member 45. The gasket 51 is of a height such that the lower end of the tubular member 45 contacts with it before the lower ends of the angle irons a and 11 reach or contact with the bottom of the casing or inclosure 2. The result of this is that a considerable proportion of the weight of thecontainer and the purifying material therein is supported upon the said tubular member so that the latter presses firmly upon the gasket 51 to form a gas tight closure between the said gasket and the lower end of said tubular member. The gas afterit has percolated through the purifying material of the container passes out through a tubular member 45 and into the outlet member 55 and thence into an adjoining compartment through an opening as shown in Fig. 2. The action of the purifying material contained in the con-' tainer of the last mentioned compartment is identical with that just'described. Instead of passing to a second compartment and being further purified by purifying materials therein the gas may be conducted directly to a storage tank or reservoir ready for use or may be conducted directly to the point where it is to be used.

It will be understood that any other suitable means than that shown may be employed for inserting a container into and removing it from a compartment and also that instead of collapsing or taking it apart for the purposeof discharging or removing the material therefrom it may be otherwise emptied, as by inverting it.
